Quantum key synchronization within a server-cluster

ABSTRACT

A system for quantum key synchronization within a server-cluster is provided. The system may include a plurality of silicon-based servers encapsulated in quantum cases. Each quantum case may include a quantum tunneling transmitter module, a quantum random number generator and a quantum entanglement module. The quantum cases may communicate with each other via the quantum tunneling transmitter module or any other suitable manner. The quantum cases may only communicate with cases with which they are entangled. Therefore, in the event of a compromise on one of the servers, the quantum entanglement module, included in the case that encapsulates the compromised server, may become disentangled, and therefore not be able to communicate with the other servers included in the cluster using an internal communications protocol.

FIELD OF TECHNOLOGY

Aspects of the disclosure relate to cryptographic keys. Specifically, this disclosure relates to cryptographic keys used with quantum-resilient computing systems.

BACKGROUND

Many transactions are processed using one or more digital devices. Such transactions may be known as digital transactions. Every digital transaction generates data. The generated data is processed, transformed and stored. There is value associated with each generated data element. The value may be a personal value. The value may be a historical value. The value may be any suitable value.

While data analytics and big data have revolutionized the modern world, the concentration of data has also enabled an era of digitally-based criminal activity. Therefore, entities may be required to consider criminal activity in addition to various other factors when planning the architecture of their systems that process, transform and store data. As such, entities may consider various concerns associated with data processing. These concerns may include complexity, cost, availability, redundancy, integrity and confidentiality. These concerns may be prioritized based on level of risk.

The architecture of a low-risk system may prioritize complexity, cost or integrity, and therefore, have a centralized system. In such a system, data may be stored and processed in a single computer or single computer system.

The architecture of a high-risk system may be a distributed system that includes redundant data. In such a high-risk system, availability and confidentiality may be a system priority, and complexity may not be a system priority. As such, any system that is not centralized on a single node, may add a level of complexity and may require some level of synchrony to operate. Synchrony may be a rate and sequence by which the two nodes communicate data between each other. The lowest level of synchrony may be that both systems start from the same place and never communicate again with each other. The highest level of synchrony may be that both systems communicate with each other in real-time.

One of the main benefits of a distributed and decentralized system is the ability to access a copy of data that is included on a node that experienced a failure. Therefore, a distributed and decentralized system may be more secure than a centralized system by design.

Additionally, recently, quantum computing has become more viable. Quantum computing is the use of quantum-mechanical phenomena such as superposition, spin and entanglement to perform computations. The smallest bit in a quantum computer is called a qubit. Quantum computing differs from classical computing in such a way that each qubit can be in a zero state and a one state at the same time.

Quantum entanglement may be a property in which quantum particles become entangled. Once entangled, the particles remain connected so that actions performed on one affect the other, even when separated by great distances. A quantum particle may have certain characteristics. One of the characteristics may be a spin. The spin may be determined to be spin-up or spin-down. The rules of quantum physics state that an unobserved quantum particle, such as a photon, exist in all possible states simultaneously, but, when observed or measured, collapses into one state. When the spin of one entangled particle is measured, the paired particle is observed to have the exact opposite spin. Therefore, if one particle is observed in a spin-up state, its entangled particle is observed in a spin-down state. This phenomenon occurs even when the particles are separated by large distances.

It would be desirable to utilize quantum entanglement properties to maintain the security of a distributed architecture system.

SUMMARY OF THE DISCLOSURE

DETAILED DESCRIPTION

Apparatus and methods for quantum key synchronization within a server-cluster are provided. The system may include a plurality of silicon-based servers. Each of the silicon-based servers may be encapsulated in a quantum case. Each quantum case may include a quantum tunneling transmitter module.

Each quantum case may also include a quantum random number generator. The quantum random number generator may be operable to generate quantum-resilient random numbers. The quantum-resilient random numbers may be for use in quantum-resilient cryptographic schemes.

Each quantum case may also include a quantum entanglement module. The quantum entanglement module, included in each quantum case, may be entangled with other quantum entanglement modules, included in other quantum cases. In some embodiments, each quantum entanglement module may be entangled with every other quantum case within the server-cluster. In certain embodiments, each quantum entanglement module may be entangled with a centralized silicon-based server within the server-cluster.

In some embodiments, a first quantum case may communicate with a second quantum case. In some embodiments in which disentanglement is a sign of compromise, the communication may determine whether the second quantum case is in a state of entanglement with the first quantum case. The communication may identify the security of the second quantum case. In the event that the second quantum case is determined to be in a state of entanglement with the first quantum case, the first quantum case may ascertain that the second quantum case is secure. In the event that the second quantum case is determined to be detangled from the first quantum case, the first quantum case may ascertain that the security of the second quantum case has been compromised.

There may also be an additional security module for advancing security of quantum cases that are entangled with one another. A security module, within a first quantum case, may identify, using communications such as those described above, a second quantum case that has been compromised. The security module, within the first quantum case, may verify that the second quantum case has been compromised. In response to such a verification, the first quantum case may disentangle from the second quantum case and/or disable communications between the first quantum case and the second quantum case.

The quantum random number generator, included in each quantum case, may be operable to generate quantum-resilient random numbers. The quantum-resilient random numbers may be used as encryption keys.

There may be different modes to determine which case generates the encryption key to be adopted by all of the other cases. Different exemplary modes are described below.

In one mode, the quantum case that generated the quantum-resilient random number may transmit the generated quantum-resilient random number to the other quantum cases that encapsulate the plurality of silicon-based servers. The quantum cases that encapsulate the plurality of silicon-based servers may be operable to replace a module for dynamic encryption with the quantum-resilient random number. The quantum cases that encapsulate the plurality of silicon-based servers may utilize the quantum-resilient random number to encrypt messages transmitted to a location external to the server-cluster. The transmission may be via the quantum tunneling transmitter module included in each case.

In another exemplary mode, preferably in response to a passage of a predetermined time period from a first quantum case transmission of the quantum-resilient random number, a quantum random number generator, included in a second quantum case, may generate a second quantum-resilient random number. The second quantum case may transmit the generated quantum-resilient random number to the quantum cases that encapsulate the plurality of silicon-based servers. The quantum cases that encapsulate the plurality of silicon-based servers may adopt the second quantum-resilient random number as an encryption key. The quantum cases that encapsulate the plurality of silicon-based servers may replace the module for dynamic encryption with the second quantum-resilient number.

When a second silicon-based server included in the server-cluster is corrupted, the quantum entanglement module included in the quantum case of the second silicon-based server is disentangled from at least one quantum entanglement module within the server cluster. In response to the disentanglement, the second silicon-based server is prevented from receiving quantum-resilient random numbers from other servers in the server-cluster. Such a mode may protect the remaining servers in the server-cluster from becoming corrupted or compromised as a result of a corruption or compromise on one of the servers.

In some embodiments, a centralized silicon-based server included in the server-cluster is entangled with all cases within the server-cluster. In such an embodiment, the centralized silicon-based cluster may be notified when a server becomes corrupted or compromised. In this embodiment, each server included in the server-cluster may not be entangled with all of the other servers included in the server-cluster. The single centralized server-cluster may maintain a record of the servers and their states—i.e., entangled or disentangled. In such an embodiment, the centralized server may also transmit the quantum-resilient random number to the servers within the server-cluster.

In some embodiments, each silicon-based server may be entangled with at least one other silicon-based server within the server-cluster. In such an embodiment, each silicon-based server may communicate with a predetermined silicon-based server, and thereby, each server is notified on the updated quantum-resilient random number.

It should be appreciated that quantum tunneling may be the method of transmission used to transmit data between cases. Quantum tunneling may also be the method of transmission used to transmit data between a server within the server-cluster and a server external to the server-cluster. The data being transmitted may be an encrypted message or a quantum-resilient random number. The quantum tunneling transmitter module within each case may transmit the data.

In some embodiments, the quantum cases that encapsulate the plurality of silicon-based servers generate a combination of a silicon-based server identifier with the quantum-resilient random number. The quantum cases may adopt the combination of the silicon-based server identification and the quantum-resilient random number as an encryption key. Each of the silicon-based servers may replace the module for dynamic encryption with the combination of the silicon-based server identifier and the quantum-resilient random number. The silicon-based server identifier of each silicon-based server may be available for retrieval from the other silicon-based servers via the quantum entanglement module.

The combination of the silicon-based identifier and the quantum-resilient random number may be used to encrypt messages being transmitted from the server. The messages may be internal to the server-cluster. The messages may be external to the server-cluster. The servers within the server-cluster may be able to decrypt the messages because each server may determine the encryption key. The encryption key may be determined as follows: the receiving server may determine the identifier of the transmitting server based on transmitting server included in the message and the receiving server may combine the server identifier with the quantum-resilient random number that is shared between all of the servers on the server-cluster. Thereafter, the receiving server may determine the encryption key. The receiving server may use the encryption key to decrypt the message.

In some embodiments, other combinations may be used. Such combinations may include a hash of the silicon-based server identifier with the quantum-resilient random number.

Illustrative embodiments of apparatus and methods in accordance with the principles of the invention will now be described with reference to the accompanying drawings, which form a part hereof. It is to be understood that other embodiments may be utilized and structural, functional and procedural modifications may be made without departing from the scope and spirit of the present invention.

The drawings show illustrative features of apparatus and methods in accordance with the principles of the invention. The features are illustrated in the context of selected embodiments. It will be understood that features shown in connection with one of the embodiments may be practiced in accordance with the principles of the invention along with features shown in connection with another of the embodiments.

Apparatus and methods described herein are illustrative. Apparatus and methods of the invention may involve some or all of the features of the illustrative apparatus and/or some or all of the steps of the illustrative methods. The steps of the methods may be performed in an order other than the order shown or described herein. Some embodiments may omit steps shown or described in connection with the illustrative methods. Some embodiments may include steps that are not shown or described in connection with the illustrative methods, but rather shown or described in a different portion of the specification.

One of ordinary skill in the art will appreciate that the steps shown and described herein may be performed in other than the recited order and that one or more steps illustrated may be optional. The methods of the above-referenced embodiments may involve the use of any suitable elements, steps, computer-executable instructions, or computer-readable data structures. In this regard, other embodiments are disclosed herein as well that can be partially or wholly implemented on a computer-readable medium, for example, by storing computer-executable instructions or modules or by utilizing computer-readable data structures.

FIG. 1 shows an illustrative diagram. Server-cluster 102 may include server, computer or other device 104. Server-cluster 102 may also include server, computer or other device 114. Server-cluster 102 may also include server, computer or other device 118. Device 104 may be encapsulated within quantum case 106. Device 114 may be encapsulated within quantum case 116. Device 118 may be encapsulated within quantum case 120.

Quantum cases 106, 116 and 120 may each include a quantum random number generator, a quantum tunneling transmitter module and a quantum entanglement module. The quantum random number generator may generate random numbers that are quantum resilient—i.e., cannot be easily determined using quantum computers. The quantum tunneling transmitter module may transmit messages between devices within the cluster and external to the cluster. The quantum tunneling transmitter module may utilize quantum tunneling properties to execute the transmission. The quantum entanglement module may include one or more entangled particles. Each of the entangled particles may be entangled with another quantum entanglement module included in another case.

It should be appreciated that there may be distance between devices 104, 114 and 118. The distance may be shown at 108, 110 and 112. The distance may be a relatively large distance. The distance may be a relatively small distance. However, devices 104, 114 and 118 may continue to operate as a server-cluster because the quantum entanglement modules within cases 106, 116 and 120 remain entangled, and therefore, the devices remain in communication. If, the quantum entanglement modules become disentangled, the devices may no longer be in communication. Disentanglement between entanglement modules may indicate that a device has become corrupted.

FIG. 2 shows an illustrative diagram. The illustrative diagram may include quantum superposition, as shown at 202. The rules of quantum physics state that an unobserved quantum particle, such as a photon, exist in all possible states simultaneously, as shown at 204. However, when observed or measured, the quantum particle collapses into one state, as shown at 206 (spin-down).

Quantum entanglement, shown at 208, may occur when two quantum particles become connected. A laser beam fired through a certain type of crystal can cause individual photons to be split into pairs of entangled photons. A pair of entangled particles may be shown at 210.

FIG. 3 shows a high-availability architecture. High-availability architecture is an approach of defining the components, modules or implementation of services of a system which ensures optimal operational performance, even at times of high loads. Devices and/or servers 302, 304, 306, 308, 310, 312, 314 and 316 may communicate with each other in order to provide the high-availability architecture. Each of devices and/or servers 302, 304, 306, 308, 310, 312, 314 and 316 may be in communication with one or more of the other devices and/or servers. Communication with multiple devices may provide greater load balancing and fault tolerant capabilities.

FIG. 4 shows a centralized database architecture. The centralized database architecture may include a central location, shown at 402. Central location 402 may include substantially all of the data files associated with the system. Devices 404, 406, 408, 410, 412 and 414 may access central location 402 in order to retrieve, read, write, update or store data files.

In one embodiment, devices 404-414 may be encased in quantum cases. In such an embodiment, each of the device cases may communicate with central location 402, or with a quantum case that encases central location 402. Central location 402 may communicate a quantum-resilient cryptographic key and/or quantum-resilient cryptographic key updates to each of the device cases in communication with central location 402.

FIG. 5 shows a distributed database architecture. The distributed database architecture may include multiple devices, shown at 502-524. Each of devices 502-524 may include a portion of data files may be in communication with one or more of the other devices.

It should be appreciated that each data file may be included on multiple devices. Therefore, in the event of a failure of one or more devices, access to the data files included on a failed device may remain available.

In some embodiments, each of devices 502-524 may be encapsulated in a quantum case. Each of the quantum cases may communicate with one or more other quantum cases. In such an embodiment, the quantum cases may communicate quantum-resilient cryptographic keys to other quantum cases with the distributed database. It should be appreciated that, in some embodiments, the quantum-resilient cryptographic keys may only be transmitted to other quantum cases that are entangled with at least one other quantum case within the distributed database.

Thus, systems and methods for quantum key synchronization within a server-cluster have been provided.
